POOR VISUAL OUTCOMES IN SYPHILITIC UVEITIS ASSOCIATED WITH METHAMPHETAMINE USE: A CASE SERIES.

Purpose: This study aimed to investigate the potential link between methamphetamine use and infectious syphilitic uveitis through a retrospective chart review of four patients with both conditions.

Methods: A retrospective chart review was conducted on four patients with a history of methamphetamine use and presented with vision loss at an emergency department or clinic that was ultimately diagnosed as syphilitic uveitis.

Results: The average age of the four patients was 41.5 ± 9.8 years, and each presented with symptoms of blurry vision after an average of 3 weeks. Clinical and serologic examinations revealed variable severity of syphilitic uveitis in each patient, and a confirmed history of methamphetamine use was found on a review of social history. Each patient had worsening visual outcomes after the initial presentation and diagnosis.

Conclusion: Syphilitic uveitis is a challenging diagnosis because of its similarity with other ocular pathologies. This case series highlights the importance of maintaining a high level of suspicion for syphilis in patients with a history of methamphetamine use and uveitis to enable rapid treatment and prevent visual decline. The poor visual outcomes observed in these four patients underscore the significance of identifying and treating syphilitic uveitis promptly in this population and the barriers to treatment completion.
